Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X800S-06B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X800S-06B is a genuine double-acting profile-type cylinder with a Ø50mm bore, 800mm stroke and a built-in 4M210-06 5/2 solenoid valve — it switches itself from one coil signal, so no separate remote valve or extra plumbing is needed.

About the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X800S-06B
The SAUF50X800S-06B is a double-acting profile cylinder with a built-in AirTAC 4M210 5/2 solenoid valve on the cap. One coil signal drives the actuator, eliminating remote plumbing and saving a manifold slot. The extruded aluminum barrel makes it shorter than an ISO 15552 cylinder of the same bore. This 50mm bore unit has a 1/4" cylinder port, an M16x1.5 rod thread, and a 21mm adjustable cushion.
It operates on DC24V with terminal entry and includes a piston magnet for CMSG/DMSG/EMSG switches. The 4M210-06 valve has a 1/8" port, Cv 0.78 flow, and handles 5 cycles/sec. Size force within the 0.15-0.8 MPa valve window. At 0.5 MPa it pushes 982 N and pulls 825 N. The safe working load is roughly 589 N, allowing a vertical lift of about 50 kg with a 2:1 margin.

The cylinder rates to 1.0 MPa but the built-in valve operates 0.15–0.8 MPa, so run the assembled SAUF at 0.15–0.8 MPa. Default: rod retracts when the coil is energised (reconfigurable to extend). Specs follow the official AirTAC SAUF datasheet. Port options: PT / G.
Theoretical Output Force (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 825 N |
| 0.7 MPa | 1374 N | — |
Sized within the valve's 0.15–0.8 MPa range. Actual usable force is lower than theoretical due to friction and back-pressure.

SAUF does not hold its load without air — the valve routes air, it is not a lock. For a held load, add an external rod lock or a pilot-operated check valve.
Where the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X800S-06B Is Used
Decentralized Conveyor Divert
Mounts directly at the divert gate. One DC24V signal actuates the 800mm stroke without running long tubing back to a central manifold.
Remote Machine Gate
Ideal for isolated access doors on large equipment. The built-in 4M210 valve switches locally, saving manifold slots and installation time.
Vertical Material Lift
Lifts up to 50 kg vertically with a 2:1 safety margin at 0.5 MPa. Use the -S magnet for end-of-stroke confirmation.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X800S-06B the Right Choice?
Size this 50mm bore against its neighbours: a 40mm bore offers 628 N push, while a 63mm bore provides 1559 N at 0.5 MPa. This model pushes 982 N and pulls 825 N at 0.5 MPa. Confirm the DC24V terminal entry and PT threads meet your control spec. The cylinder body rates to 1.0 MPa, but you must size force within the built-in valve's 0.15-0.8 MPa working range. By default the rod retracts when the coil is energised; reposition the valve to extend on signal. The valve routes air, so for load holding on air loss add an external rod lock or pilot-operated check valve. With an 800mm stroke, use external guides to prevent rod bending and side loads.
Quick checklist
- ✓ Force at 0.15–0.8 MPa
- ✓ Coil voltage matches panel
- ✓ Terminal vs grommet entry
- ✓ Retract- or extend-when-energised
- ✓ Load-holding → external rod lock
Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X800S-06B FAQ
It pushes 982 N and pulls 825 N at 0.5 MPa. The built-in valve is a 4M210-06 (1/8" port, Cv 0.78, 5 cycles/sec) running on DC24V. Although the cylinder body rates to 1.0 MPa, the assembled unit must operate within the valve's 0.15-0.8 MPa range. The cylinder port is 1/4".
By default the rod retracts when the coil is energised; you can reposition the valve to extend on signal. The 5/2 valve only routes air, so it is not a load lock. The piston will drift on air loss, requiring an external rod lock or pilot-operated check valve to hold a load.
